MediaMonkey see, MediaMonkey do
We're going to use MediaMonkey to embed album art in your music
files. This is a bit different from Windows
Media Player's messy default method of adding art as separate files within each album folder. The advantage of embedding is that all desktop music players (including Windows Media Center) and portable devices (like the Creative Zen Vision:M, which is notoriously finicky when it comes to album art) should be able to display the art, because it's, well, embedded.
